National Park Service. The Park Service also proposed extending East Capitol Street onto the reclaimed land and then over the Anacostia River, and building a complex of sports stadiums, an armory, an outdoor theater, a swimming pool, an ice skating rink, and athletic fields on the flats. Legislation proposing a bridge across Kingman Island and stadium complex in Anacostia Park was submitted to Congress, which did not act on the proposals. The first nine holes of Langston Golf Course were built on the north end of Kingman Island in 1939, and the back nine on the lake's western shore in 1955. Work on the islands stopped in 1941 due to budgetary and resource shortages associated with the advent of World War II. In August 1947, construction of an airport on Kingman Island was again proposed, but the NCPPC disapproved the proposal in December. The project was proposed again in August 1948, because dredged material was still being placed on Kingman Island to build it up and large portions of the island remained undeveloped. In 1946, the last pair of bald eagles on the Anacostia River abandoned their nest on Kingman Island. Although a bird watcher claimed to have seen a bald eagle nest on the Anacostia River in 1988, the bald eagle did not return until transplanted eaglets returned to the river as adults in 2004. 1950s–60s The city finally extended East Capitol Street across the Anacostia River and Kingman Island in 1955. That 1934 proposal was finally approved by city and federal planners in 1949. Construction required that of lake bottom be dredged from Kingman Lake and replaced with sand and gravel to create a gently curving peninsula that extended into the western side of the lake. of fill would be used to raise the peninsula above the low water mark, so that the bridge's western approaches could built on the new land. The Whitney Young Memorial Bridge opened in November 1955. Reclaimed land on the western shore of Kingman Lake became the site of RFK Stadium in 1957. D.C. officials, who had been seeking a site for a large all-purpose sports stadium since the early 1930s, finally won support from the U.S. House of Representatives for a stadium at Anacostia Park in January 1957. D.C. Commissioners approved the site a few days after the House vote, and the District of Columbia Stadium (renamed Robert F. Kennedy Stadium in
